3.12.4 Troubleshoot Speakers

Even though the video technically doesn't talk about this, this is essentially what it's about.

This goes under "try the simple fixes first" section.

Check the Speakers

Check if they're plugged into the right audio jack on the PC. Make sure that the physical volume knob on the speakers is turned up and that they're turned on (if they have a power switch on them). If they have an external power port, make sure they're plugged in correctly too.

Check Windows Device Manager

Verify that Windows detects the connected speakers and that the correct drivers are installed and loaded. If there's an error message, something has gone wrong no mames wey. It's a 50/50 chance between the audio hardware or the driver.

The easiest solution would to be installing or updating the latest drivers from Windows. Otherwise, check the speakers for damage and consider replacing them.

Check Installed Codecs

For every audio file format, Windows requires it's audio codec to be installed. If you try to play an audio file without it's complementary codec, Windows won't play the audio file. The list of installed codecs can be found in Windows Media Player (application) > Help > About WMP > Technical Support Information > Audio Codecs

Check BIOS/UEFI

BIOS has a setting where you can toggle on what audio interfaces the system will use. For example, if you had two audio interfaces, a USB headset and stereo speakers connected through audio jacks, you can disable one of them and force the system to only output audio to the other. If you then try to use the disabled one, you'll get radio silence (dad joke, knee-slapper).

Check the Audio Card

If you have a dedicated audio card, check whether or not it's seated properly or experiencing electromagnetic interference, as those can result in bad audio. EMI sources can come from inside the PC, from the disk drives and from the power supply.
